Description
Technical field
The utility model relates to the mould applications for punching press moulding, is specially a kind of diel for hemisphere build part that adopts guide pillar and bolt.
Background technology
Punching press is one of most important processing method in mould industry.The range of application of punching press is very extensive, and according to statistics, in all electronic products, the quantity of stamping parts (comprising sheet metal component) accounts for 85% of part sum, in all steel, has 60%～70%, sheet material, and major part in sheet material is through punching press manufactured goods.But the current mould for punching press, because closing precision is limited, in particular for stamping surface with radian during as ball-type, dome-type part, because piece surface has radian, the easy sideslip of mould, crooked when punching press, cause Product Precision low, affected the use of punch process.
Utility model content
In order to overcome the defect of prior art, a kind of easy to use, closing precision is high, part quality is high punching press mould is provided, the utility model discloses a kind of diel for hemisphere build part that adopts guide pillar and bolt.
The utility model reaches goal of the invention by following technical solution:
A kind of diel for hemisphere build part that adopts guide pillar and bolt, comprise cope match-plate pattern and lower bolster, cope match-plate pattern is relative with lower bolster and be arranged in parallel, it is characterized in that: also comprise bottom plate, stripper, stripper mold insert, punch, concave template, set bolt, alignment pin, contour grip assembly and discharging spring
In bottom plate, stripper, punch and concave template, be all provided with die cavity, the die cavity of punch is dome-type, the die cavity of concave template is the plane that has through hole, and the die cavity of punch is the through hole to concave template die cavity just, and the through hole of the die cavity of punch and concave template die cavity matches each other;
Bottom plate is fixed in the upper plane of lower bolster, and punch is fixed in the die cavity of bottom plate, thereby set bolt is connected and fixed this three through lower bolster, bottom plate and punch successively;
Stripper is fixed in the die cavity of punch, stripper mold insert is fixed on stripper, and the forming direction of punch and concave template is consistent, thereby contour grip assembly is connected location with stripper by this three through lower bolster, bottom plate successively, between bottom plate and stripper, be embedded with discharging spring
Concave template is fixed on the lower plane of cope match-plate pattern, thereby set bolt is connected and fixed the two through cope match-plate pattern and concave template successively, thereby alignment pin is connected location with concave template by the two through cope match-plate pattern successively.
Described employing guide pillar and the diel for hemisphere build part of bolt, it is characterized in that: after the die cavity of punch and the die cavity of concave template are aligned with each other, the gap of both binding faces is at 1.5mm to 2mm, punch embeds after the die cavity of bottom plate, gap between punch and bottom plate is not more than 0.01mm, 0.03mm, at 0.02mm to 0.04mm, is generally selected in gap between punch and stripper.
When the utility model uses, stripper, concave template and punch are implemented be connected and locate with set bolt by alignment pin, make concave template and punch position fixedly avoid mould shift defect, raw material are sent into the die cavity of concave template after locating via concave template.
The beneficial effects of the utility model are: simple in structure, closing precision is high, and part quality is high.
